Definitions

  • Zirconium silicate which includes the coloring particles, has proven itself as a coating substance.
  • the zirconium silicate formation and the inclusion of the coloring particles take place in a solid-state reaction at 750 - 1400 o C from a source of silicon dioxide and a source of zirconium dioxide, usually directly from SiO2 and ZrO2, in the presence of mineralizers.
  • all conceivable colored compounds during the formation process of the zirconium silicate shell can by no means be enclosed by it in a sufficient amount for pigment purposes.
  • the coloring components or their starting compounds can namely in many cases delay or prevent the formation of ZrSiO4 from SiO2 and ZrO2, or the colored compounds are not coated at all and thus the desired pigment properties are not achieved.
  • the spinel-containing inclusion pigments according to the invention generally have D Werte values in the range from large 2 to 20 ⁇ m, in particular 8 to 15 ⁇ m. They are suitable for coloring glazes, enamels, decorative colors and for producing sharp-contoured ceramic decorations, which do not cause any color change during baking and do not bleed out.
  • the inclusion pigments according to the invention can also be used in other substrates, such as plastics, lacquers and printing inks.
  • the non-included spinel tested for comparison leads to the release of Fe and Ni ions and to a color change to yellow olive brown.
